Hi everyone, hoping someone can help me...

I have a 2002, Jeep Grand Cherokee 2002, 4.0

The check engine light has been on for a while with a a code that I have been meaning to fix -

0455 - Evaporative Emission Control System Leak Detected (large leak)

Yesterday I went to start the car and nothing... everything seems fine, the instrument lights come on - everything works - radio, windows and the voltage meter is reading 14v which it always reads...

So I looked at the codes to see if that could shed some light on it and I got a bit of a shock with the following codes....

1682 - Charging System Voltage Too Low
0753 - Transmission 3-4 Shift Sol/Transmission Relay Circuits
1282 - Fuel Pump Relay Control Circuit
0161 - O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
0463 - Fuel Level Sending Unit Volts Too High
0838 - Four Wheel Drive (4WD) Switch Circuit Low
0837 - Four Wheel Drive (4WD) Switch Circuit Range/Performance

Please help I havent a clue where to start! it is not even a four wheel drive so I dont know how I am getting the four wheel drive codes.

I have checked the battery terminals, tried taking them off and cleaning but still the same...

Thanks in advance

Start by load testing the battery. Head lights and radio do not mean squat.

The battery is only a couple of months old and I have had it tested... any other ideas?

Check the charging.
